Answer:
M=-8
Step-by-step explanation:
21+6m=3(m−1)
Step 1: Simplify both sides of the equation.
21+6m=3(m−1)
21+6m=(3)(m)+(3)(−1)(Distribute)
21+6m=3m+−3
6m+21=3m−3
Step 2: Subtract 3m from both sides.
6m+21−3m=3m−3−3m
3m+21=−3
Step 3: Subtract 21 from both sides.
3m+21−21=−3−21
3m=−24
Step 4: Divide both sides by 3.
3m/3=-24/3
M=-8
C. 21/45
If you multiply both the 7 and 15 by 3, you get 21 and 45.
$67.50 for three pairs of pants. $97.50 for five pairs of jeans. For all of these the price would be $165.00
Answer:
A person completed 10 homework questions in 9 minutes.
=> In 1 minute, that person could handle the number of homework questions:
N = 10/9 = ~1.1 homework question.
=> Rate = ~1.1 (hw/min)
Hope this helps!
